I’m fond of images of trees, but
mostly if they are forensic or employed to display relationships between ideas
or data. One of my favorites for the
former is this great image from Peter Guillet’s
Timber Merchant's Guide. Also, a Table, Whereby, at One View, May Be
Seen the Solid and Superficial Measure of Any Square or Unequal Hewed Logs or
Plank...1 (printed
in Baltimore by
J. Longrove in 1823).
Guillet was basically
a tree dissector, a harvester of wood for the construction of naval ships. His book shows how to make the best—the most
efficient—use of various varieties of trees, displaying how to employ different
sections of trees for different parts of a ship. The book must’ve been an
indispensable handbook down at the mill.
At the every least, it certainly introduced a novel way of looking at
trees.
This tree2 was a figure drawn by biologist and eminent
Darwinian Ernst Haeckel3 (1834-1919), the branch spaces relating to intervals
which were unrepresented in the fossil record. The image was perhaps the most
popularly successful part of his two-volume double-wristbender—it was a
difficult book, not well written or presented, with Charles Darwin himself finding
it “impossible to read”.
The second tree, offered by Haeckel in his The
Evolution of Man (1879): shows the general evolutionary progress of
living things culminating in man, the hopeful and suspected end (or height, or
crowning achievement) of the process of evolution. Which is a little odd, come to think of it,
to have there be nothing above man, not even a space for unimaginable improvement,
not even a single unused branch to express the possibility of supra-human
development.
By far the most complex of the tree of life series is the
tree ring of life, an exploding and explodably adaptable image generated by the
Life Website which begins at the beginning, with "life" itself.4
The coal tree of life is a particularly confusing image. Even though this is a simple classification scheme, and a
very-well designed graphic at that, the use of the tree describing the genealogy
of coal by-products just seems, well, wrong. The use of the tree in defining a visual phylogenic interrelatedness of
living things appears pretty much for the first time in the first edition of the
Origin of Species in 1859, and it is the only diagram that
appears in the
book. (And by this I mean the use of the tree-scheme for scientific
purposes: the tree of life of course has been used for many, many
centuries, the philosophical design woven into the fabrics and incised
into the stone of many cultures. It sort of appears in print in
classification usage at least by the wily and polymathic Athansius
Kircher, who used it to display the elements in a Kabbalistic Tree of
Life some 350 years ago.)
The Verkaufsvereinigung fuer
Teererzeugnisse (of Essen) used this idea in
1922, publishing the ad for their company in the Illusrtriete Zeitung (Leipzig). The great tree spring from a bed of coal (“kohle”)
exhibiting the “stammbaum der nebenerzeugnisse” (roughly the “pedigree of our
product”), with the trunk being gas, branching out into tar, coke and cyan and
so on. Even though it’s the lifeblood of
the continuing industrial revolution, and even though we’re hundreds of years into
a deep need with the products, the use of the tree just seems antithetical to it
all on all levels of recognition, especially now.
Then of course there's the Darwin tree, an incredible diagram from his notebooks, prefaced with the extraordinary understatement, "I think".
There will be more of these tree to come, shortly, including a tree of dermatological disease and some Kabbalisitc trees of life, but they'll have to wait for right now.
Notes:
1. The full title, as follows: Timber Merchants’ Guide. Also, a table,
whereby, at one view, may be seen the solid and superficial measure of any
square or unequal hewed logs or plank, from one to forty-seven inches. Also,
plates representing the figures of the principal pieces of timber, used in
building a seventy-four gun ship of the line, in standing trees.
Also, Guillet had some interesting ideas on the conservative use of forest
lands (from Franklin Hough’s Report upon Forestry, a government document
printed in 1876):
"Individuals wishing to make
the most of their woodlands will find it very profitable to cut their timber by
sections, sparing to very acre ten or twelve of the most promising size white
oaks or pines, whichsoever the soil will produce best; range the order of their
lands so as to cut a section every year. For example, say a man has 200 acres of
woodland divided into sections of 10 acres each, then, by cutting one section
every year, he would have young timber twenty years old, which makes excellent
firewood, and I should say that in common lands wood of twenty years' growth
would yield 15 or 20 cords of firewood per acre, besides fencing-timbor
sufficient to always keep in good repair an inclosure of 200 acres. Then the 10
or 12 trees growing in reserve will, at the end of 80 or 100 years, furnish
timber fit to make shipping or staves. Where land has become useless from long
cultivation, a little trouble only is necessary to make it productive and
profitable to the owner. By inclosing it for a few years and encouraging the
growth of the most promising younj* trees, which will generally spring np
spontaneously, all the advantages above described will be derived from it,
which is certainly the best way that worn-out or sterile land can be disposed
of. Such a course recommended to and adopted by individuals wonld not only be
to their own private gain, but also of great public utility."

4. Explanation of the second diagram, as follows from Discover Life: "Phylogeny
is the organizing principle of modern biological taxonomy, and a guiding
principle of modern phylogeny is monophyly: a monophyletic group is considered
to be one that contains an ancestral lineage and all of its descendants. Any
such a group can be extracted from a phylogenetic tree with a single cut. The
tree shown here provides a guide to the relationships among the major groups of
the extant (living) organisms in the Tree of Life as we have presented them
throughout this book. We do include three groups that are not believed to be
monophyletic; these are designated with quotation marks.” See also HERE for a different view of this diagram.
